BROTZ, OF .KOHLEB YWISGONSIN, ASSIGNOR TO KOHLER COMPANY, OF IKOHLER, WISCONSIN,-A CORPORATION OF WISCONSIN BA'iI-I WITI-I INTEGRALWASTE Application filed Iluly Z 1928. Serial No. 289,911.

This invention has for its object toprovide a bathtub having embodiedwithin it the drain, overflow, trap and wastecontrol, there bysimplifying installation by reducing to a minimum theplumbing'connections necessar Xnother object of the invention is to soembody these necessary features in the bathtub construction that theyform an integral .10 part of the bathtub, the shell'or casing thereofbeing a part of the same casting with the bathtub.

Another object of the inventionistocon dense the space occupied bythe'se necessary adjuncts to the bathtub whereby the tub may be fittedinto close quarters. l

Another object of the invention-is to provide ready access to the trapand the control valve and the removal of the latter with its valve seatfor cleaning and repairing.

. With the above and other objects in view the invention consists inthe'bath with integral waste as herein claimed and allequivalents.

Referring .to the accompanying drawings in which like charactersof'reference indicate the same parts in difierent views,

Fig. ljis a vertical sectional viewof the end of a bathtub constructedin accordance with this invention, the sectional plane thereof beingindicated by the line 11 of Fig. 3

Fig. 2 is a sectional view thereof on the plane of line 2-2 of Fig. 1;

Fig. 3 is an end elevation; Fig. 4 is a sectional view on the plane ofline 44 of Fig. 1;

Fig. 5 is a sectional view showing a modified form of waste valveoperating mechanism;

Fig. 6. is a rear view of the cover-plate for the hand hole, and i Fig.7 is an enlarged sectional view of the valve seat. I

In these drawings, 10 indicates a bathtub of cast ironwithvitreousenamel surface having formed integral therewith in the samecasting the casing and conduit structure of the waste control inaccordance with the present invention. -'The drain outlet is formed inthe bottom or end or, .as, shown, in'both, by slots 11 in the tub wallitself, so that the. 1onbeing siphoned.

v valve chamber 14 in the center line of thetub is a trap 15communicating therewith through a passageway 16 forming a weir tomaintain a water level, as shown, and at the side and front of this trapare threaded openings into whichmaybe screwed an elbow 17 forming awaste coupling and a screw plug 18 forming a closure, the two beinginterchangeable to obtain that location for the waste coupling whichis'mos't suitable. Also connecting with the trap is a vent pipe 19 toprevent the trap In the front of the valve chamber 14 there. is a handholei provided with a flanged and gasketed cover-plate 20heldj in placeby screwsto tightly seal the trapped water. This cover-plate has aprojection21 on its rear face, which terminates in a conical surface 22tightly" fitting the conical seat 13 when'the cover-plate '20 is sealedby tightening its screws. A recess 23 in the projection 21 shown aseccentric forms an extension of the waste conduit 12 1ncommunlcationtherewith. and passing vertically through the projection 21is a cylindrical opening forming a valve guide 24, in which'acylindrical valve member 25' is vertically movable. Beneath the recess23 the opening 24 is reduced in diameter to afford a conical seat 26 forthe conical valve face at the lower end of valve 25 sothat the dischargeof water from the waste conduit 12 through the recess 23 and the lowerend of opening 24 is interrupted when the valve is seated. lhe valve'isshown as of the-usual tubular form but a central passageway is notessential as there is'a free passageway around the-projection 21 for thepassage of the water from the overflow, as shown in Fig. 2. It will beunderstood from the above that the removable cover-plate for the handhole carries the valve seat with it. preferably as an integral partthereof, and forms a sealing fit with the waste conduit when thecover-plate is clamped in place.

The overflow for the tub is formed by an opening in the end wall of thetub communicating with the extension 27 of the valve chamber and isguarded by a rounded hood 28 projecting into the tub and formed integralwith the wall of the tub and said extension 27, as seen in Fig. 1, sothat water overflowing through the opening is conducted through theextension 27. to the valve chamber and out through the trap, as will bereadily understood.

For operating the valve a handle member 29 clamped on a shouldered stem30 rotatably fitting through the hood 28 serves to turn a crank 31within said hood, which crank is connected by a rod 32 with a bail 33 onthe valve. As the handle is turned the crank lifts the valve by means ofthe connecting rod, the latter being bent, as shown in Fig. 2, to followthe offset or angular shape of the valve chamber.

Provision is made for removing the valve by disconnecting thecover-plate and with-- drawing it from the valve chamber and then eitherunhooking the valve from the connecting rod 32 or disengaging theconnecting rod from the crank 31. In this manner both the valve and itsseat are removable for cleaning or repairing.

Opposite the opening for the handle stem the extension 27 has a pluggedopening 34 for use in inserting or removing the valve stem, or which maybe used as shown in Fig. 5 to receive a bearing plug having a crank stem36 turning therein for operating the valve, said stem 36 being providedwith a crank arm 37 at its outer end connected by a link 38 with anoperating means, not shown, in the wall above.

By means of this invention the bathtub is made to contain its own trapand waste and outlet fitting as an inherent part thereof, requiring onlythe coupling of the elbow 17 with the waste pipe and the coupling of thevent opening with the vent pipe to complete the waste connectionstherefor and embodying within itself the waste control and operatingmeans therefor. Also with this 1nvention the waste valve and its seatare readily accessible and the parts are so condensed that the entirewaste assembly may be placed within an ordinary wall with a minimumheight between the bottom of the tub and the sewer drain connection. Inactual practice the Water level of the trap may be half an inch abovethe bottom of the apron 39 of the tub, which is tiled into the floor,and the center line of the outlet of the trap within one and a halfinches from the enameled surface of the tub bottom. The invention alsoprovides a drain outlet formed by the enameled wall of the tub itself,obviating the necessity for the use of metal drain covers and this,together with the integral built-in guarded overflow, dispenses with allmetal attachments for the porcelain-lined tub.

Although the valve is shown as offset from the center line of thebathtub through the drain outlet, in order to accommodate the wastefitting 17 at said center line to conform with the usual roughing-inpractice, it is obvious that the valve may be located on said centerline and, by means of suitable elbows, the waste fitting may be coupledwith the sewer connection.
